It is a powerful creature that uses three different attacks: a Breath attack that is Fire-based and will damage the entire party, Earthquake, that will also target the entire party and delay their next turns, and a regular physical attack. An alternative to farming the Adamantoise for four-slot equipment is simply to buy it from Wantz at the south entrance to Macalania Woods, if the party spoke with him at Mt. Gagazet, otherwise he will disappear. He moves to Macalania after Yuna confronts Grand Maester Yo Mika.
